CVE-2026-82725 (GCVE-0-2026-82725)

Vulnerability from cvelistv5 – Published: 2026-08-31 03:09 – Updated: 2026-08-31 15:49

Title

AshPhoenix FilterForm allows filtering across non-public relationships, disclosing private related data

Summary

Authorization Bypass Through User-Controlled Key vulnerability in ash-project ash_phoenix lets an attacker who controls filter form parameters filter across relationships the resource author marked non-public, turning the returned rows into a boolean oracle over private related data. AshPhoenix.FilterForm resolved every relationship hop in the user-supplied path with Ash.Resource.Info.related/2, which traverses private relationships, and only checked the terminal field for publicity. parse_path_and_field/2 also rewrote a field naming a relationship into an extra path segment, so field=some_private_rel was accepted too. Both path and field come straight from form params, and the resulting ref went to Ash.Query.do_filter/2 without the public-only enforcement of Ash.Filter.parse_input/2. The fix resolves each hop with Ash.Resource.Info.public_relationship/2, rejecting the first non-public hop, and requires the terminal field to be public. This issue affects ash_phoenix: from 0.6.0-rc.1 before 2.3.25.
